♠ GreenChip isilawuli sohlengahlengiso esidibanisa kabini
I-TEA1995T yimveliso yokuqala yesizukulwana esitsha se-Synchronous Rectifier (SR) isilawuli se-ICs sombane wemowudi etshintshiweyo.Ibandakanya indlela yokuqhuba isango eliguquguqukayo ukuze isebenze ngokugqibeleleyo kuwo nawuphi na umthwalo.
I-TEA1995T ngumlawuli ozinikeleyo we-IC wokulungiswa okuhambelanayo kwicala lesibini labaguquli be-resonant.Inezigaba ezibini zokuqhuba zokuqhuba ii-SR MOSFETs, ezilungisa iziphumo zetephu esembindini yamajiko okutshintsha kwesiguquli.Izigaba ezimbini zomqhubi wesango zineempembelelo zazo zokuva kwaye zisebenza ngokuzimeleyo.
I-TEA1995T ingasetyenziswa kwiziguquli ze-flyback zeziphumo ezininzi kunye ne-SR MOSFET ebekwe kwicala elisezantsi.
I-TEA1995T yenziwe kwinkqubo yeSilicon-On-Insulator (SOI).
2.1 Iimpawu zobuchule
• I-Adaptive gate drive ukuze usebenze ngokugqibeleleyo kuwo nawuphi na umthwalo
• Unikezelo lwangoku kumsebenzi wokonga amandla ngaphantsi kwe-200 μA
2.2 Iimpawu zesicelo
• Uluhlu lwamandla ombane olubanzi ukusuka kwi-4.5 V ukuya kwi-38 V
• Uhlengahlengiso oluphindwe kabini lwe-synchronous lwe-LLC resonant kwiphakheji ye-SO8
• Ulungelelwaniso lolungiso lweziguquli ze-flyback zeziphumo ezininzi
• Ixhasa ukusebenza kwe-5 V kunye ne-logic level SR MOSFETs
• Amagalelo ahlukeneyo okuva umjelo kunye nomthombo wombane we-SR MOSFET nganye
2.3 Iimpawu zokulawula
• Ulawulo lwe-SR ngaphandle kobuncinci bexesha
• I-Adaptive gate drive yokucima ngokukhawuleza ekupheleni komqhubi
• Ukhuseleko lwe-UnderVoltage LockOut (UVLO) ngokutsalwa kwesango elisebenzayo
I-TEA1995T yenzelwe unikezelo lwamandla ombane.Kwezo zicelo, inokuqhuba ii-MOSFET ezimbini zangaphandle zokulungisa i-synchronous kulungiso lwee-voltages kumajiko amabini esibini e-transformer.Ezi MOSFET zithatha indawo yeediode.Ingasetyenziswa kuzo zonke izixhobo zombane ezifuna ukusebenza kakuhle okuphezulu:
• Iiadaptha
• Izibonelelo zamandla kwi-desktop yePC kunye ne-PC enye
• Izixhobo zombane kumabonakude
• Izibonelelo zamandla kwiiseva
